2008 Mazda6 and Mazda3...Interchangeable Parts?

My 2008 Mazda 6 iSport was recently in a front end collision. It still runs and drives, but not allowed on the roads. I noticed around my area, there’s alot more Mazda 3s around for parts. Are most the parts needed to repair (bumper, grille, hood) able to be put on my 6?
